Answer Posted / k.prakashchandra
You mean the secondary is delta and output is 3 phase 3
wire.Then to create neutral ,you have to connect the
terminals to 3 phase neutral forming inductor coils and use
the star point as neutral.The easiest way is to connect the
terminals to a 3phase auto-transformer of correct capacity
and use the star point for neutral

Dear All we are having a problem in G120 BOP showing alarm A0503, F0052, F0060 we can not remove fault alarm ,Please any body help us. kowsar
how does the terminal voltage of transmission lines increase when a capacitor is connected???? This happens not only in transmission lines but also in all circuits. How??? When a capacitor is connected in a transmission line, capacitor also takes energy from the same supply. But how is it able to increase the terminal voltage??? Practically What sequence of events happen during increase in voltage???

Is there a possibility to use such a treshold voltage for the NMOS part of a CMOS circuit that during the switching it will start conducting only after the PMOS part will be already closed, by this eliminating the leakedge current? Please note, I'm not asking about the well bias in standby mode, but about the "antileakedge" measures during normal operation.
Good day everyone,currently in our premise we using 30kw slip ring motor with resistance bank which we use as forward and reverse at conveyor bar handling. So,my question is how do we calculate the resistance bank which is suit the motor. Kindly,assist me... thank you
